FIELD: chemistry.
SUBSTANCE: present invention relates to a method of producing improved solid fuel. Described is solid fuel which is obtained by briquetting crushed low-grade coal, where the outer surface of the low-grade coal and the inner surface of pores of the low-grade coal is coated with a nonvolatile component contained in the low-grade coal, and content of heavy oil is less than 0.5 wt % with respect to the solid fuel.
EFFECT: low production costs and environmental load, as well as improved solid fuel.
